Let me stop you there for several reasons-
1- WDW does indeed owe people something. It's asinine for any paying customer to think they aren't owed something by giving a corporation their money. We don't approach buying any other product with this absurd attitude. You pay a premium price to enter the parks and to stay at their hotels, eat the food, etc etc. You should have expectations about what you're paying for. It is not only the right of people to evaluate whether the product is worth the cost, it is the responsible thing to do.
2- People have high expectations because those are the standards Disney set for themselves prior to two decades ago. We didn't set the standard, Walt Disney and his old guard of quality oriented executives did (again they maintained these standards up until the mid 90's despite Walt himself having long since passed). We are simply holding them to their own standards, the core philosophies of the company. It is not some unattainable goal set by unrealistic expectations. We know the amazing things they were capable of, even back when they were an infinitely less powerful and less wealthy company, they have proven themselves entirely capable of meeting and even exceeded our expectations in the past.
